- Let's be careful not to mix centuries when it comes to the
- Romans and their abuse of ships. The triremes weren't used for very
- long, being replaced by larger ships after only a few decades of use.
- The Romans liked to wage land wars with soldiers, hence they went to
- larger ships and attempted boarding techniques that looked a lot like
- any land battle. These larger ships were much more stable in open seas,
- and the attrition rate dropped accordingly. The Romans weren't much
- for sailing, but managed to get roughly 20% of their army into Britain
- without undue losses en route.
-
- In addition, around the time of Constantine the Roman army
- underwent some papyrus-pushing and was divided up a lot. The old
- method was to take 20% of a legion or cohort and move it to a trouble
- spot, thereby leaving a large garrison on the frontier. The problem
- was that the 20%, say a cohort or two, never made it back to the
- mother unit. This was recognized and the Romans wound up halving the
- size of their units but making more units -- on paper. They also
- made up a "defense in depth" arrangement, where small units manned the
- frontier and mobile reserves stayed to the rear, the idea being to move
- them to trouble spots. If that trouble spot were North Africa or
- Britain, ships were needed. Triremes being what they were, by the
- 300's or so they weren't in general usage for the Romans.

- Disclaimer: My books are at the office -- this is what I
- remember from lecture today and a class a year ago or so, and I've
- a mind like a steel sieve.
